Analysis on Growth Characteristics of Poa viridula

Growth characteristics of nutritional and reproductive tiller of Poa viridula L. were studied with no quadrate sampling method. The results showed that the number of leaves and biomass of nutritional tiller were more than reproductive plants, but the height was less than reproductive plants. The biomass and plant height of nutritional or reproductive tiller was in line with the exponential function relationship, leaf biomass and plant biomass accorded with the linear relationship. The growth of reproductive organs spike, spike length and biomass of reproductive plants conformed to the power function relationship, and had reached a very significant level.
